greenlet features and specs

  • Lightweight
    Greenlets are more lightweight than native threads as they do not require their own OS-level thread. This leads to lower memory consumption and reduced overhead.
  • Simple API
    Greenlet provides a simple and intuitive API for developers, making it easier to write concurrent code without needing to manage full coroutine structures manually.
  • Efficient Context Switching
    Greenlet allows for efficient context switching between tasks, as it operates at the application level rather than relying on the operating system.
  • Flexibility
    Developers have the flexibility to implement their own scheduling and control over execution flow using greenlets.
  • Integration
    Greenlet integrates well with other asynchronous frameworks such as gevent and can be used to build scalable, concurrent applications.

Possible disadvantages of greenlet

  • No Multi-core Support
    Greenlets run in a single operating system thread, so they do not utilize multiple cores of a CPU. This limits their ability to fully leverage modern multi-core systems.
  • Manual Scheduling
    Developers need to manage the scheduling and switching between greenlets manually, which can lead to complex code and potential errors if not handled correctly.
  • Debugging Challenges
    Debugging applications that use greenlets can be challenging due to their concurrency model and the lack of native support from some debuggers and profiling tools.
  • Compatibility
    Greenlet may not be fully compatible with all Python libraries, especially those that rely on native threads or complex event loops, potentially limiting its use in certain environments.
  • Limited Use Cases
    Greenlet is best suited for IO-bound applications and may not offer significant benefits for CPU-bound tasks, where native threading or multiprocessing could be more effective.

    Well, https://github.com/python-greenlet/greenlet has been available for quite some time in Python (gevent probably being its most used flavor). i.e.: just because it's not in the standard library doesn't mean it's not available (so, you can actually choose whether you'd like to use async/await or greenlets). - Source: Hacker News / about 4 years ago
